How to enable split screen on Xiaomi Redmi 9C: The complete guide

Modern smartphones like the Xiaomi Redmi 9C have screens and processors powerful enough to perform multiple tasks at once. A split-screen feature, also known as Split-screen, allows the user to run two apps side by side, which greatly improves productivity. Instead of constantly switching between messenger and browser, you can comfortably work in both windows at once.

However, many budget model owners have difficulty trying to activate this mode. The MIUI shell on which the smartphone operating system is based has its own window management features. On Redmi 9C models, screen splitting is activated exclusively through the menu of running apps, rather than through the display settings. This often confuses those who are used to the standard Android interface.

In this article, we will take a look at all the ways to activate multitasking, how to manage windows properly, what apps support this mode and what to do if the feature does not work, and we will also look at the hidden features of the system that will help make using a smartphone even more convenient.

Preparation of the device and compatibility check

Before you start setting up, make sure your device is ready to multitask. Xiaomi Redmi 9C runs on the basis of the MediaTek Helio G35 processor, which can cope with two light applications, but may have difficulty with heavy games. Make sure that the phone has the current version of the MIUI firmware installed, as the older version may have errors that block the Split-screen.

It's important to understand that not all programs support split screens. App developers decide whether to adapt their interface to work in a smaller window. System utilities and popular services such as YouTube, Telegram or Google Chrome are usually fully compatible with this mode.

⚠️ Note: When you run two resource-intensive applications at the same time (such as a navigator and a game), the Redmi battery 9C It can discharge faster than usual, and the smartphone itself can heat up.

For comfortable split-screen work, it is recommended to set Large font in the display settings or choose a standard size to keep the text in the reduced windows readable. This can be done by going to Settings → Screen → Text Size.

The main way to activate through the task menu

The most common and reliable method of enabling split screen on Xiaomi Redmi 9C involves using a menu of recent apps. This method does not require installing additional software and works out of the box. First, you need to open the first application that you plan to use, such as a browser.

When you start the program, don't close it, turn it over to the main screen. Now open the menu of running applications. Depending on the type of navigation you choose (buttons or gestures), this is done either by pressing a square button or swiping from the bottom up with a finger held. You will see the cards of all open programs.

Find the first app card in the list. Above the window preview is usually a small icon or app name. Click on it to pop up the context menu. In the list of available actions, select the option "Spared screen" (sometimes indicated by the icon of two rectangles), after which the selected application will occupy the top half of the display.

At the bottom of the screen, the system will suggest you select a second application from a list of recently used programs or from a full list of installed programs. Tap the desired icon, and the screen will split into two active zones.

Alternative methods and hot keys

There are other ways to quickly multitask that may be more convenient in certain situations, such as if you're already in the app, you can try using a keyboard combination, although the Redmi 9C physical button "Menu" is often reprogrammed. However, some versions of MIUI run a quick swipe.

Try swiping three fingers from the bottom up the screen. If this feature is activated in the settings, the screen will automatically split. To check and enable this option, go to Settings → Additional Features → Swipe with three fingers and select the action "Share".

• 📱 Gestures: Swipe three fingers up is the fastest way if it's tuned.
• 🔘 Menu button: In some design themes, a long press on the "Menu" button (square) inside the application also causes separation.
• ⚙️ Through settings: In the "Extended Settings" section, you can sometimes find the "Menu button settings" item, where the Split-screen function is assigned.

If the three-finger swipe doesn't work, check if the one-handed mode is on, and it can conflict with split-screen gestures, and make sure there's no thick-edged protective film on the screen that can interfere with the correct recognition of multi-touch gestures.

Window management and resizing

Once you split the screen, you have the flexibility to adjust the space, and there's a special dividing bar between the two active windows, and if you drag it up or down, you can change the proportions of the content that you display.

On the Xiaomi Redmi 9C, with its 6.53-inch diagonal, it is sometimes more convenient to give more space to one application, such as a navigation map, leaving the second window minimal for chat. Tap the dividing strip and pull it in the right direction. If you drag the strip to the edge, one application will close and the other will occupy the entire screen.

There are also often additional control buttons in the middle of the dividing strip, and clicking on the swapping icon will swap apps from the top to the bottom, and vice versa, which is useful if you need to temporarily focus on content that is in an uncomfortable zone.

Floating windows and advanced multitasking

The MIUI shell offers an even more advanced level of multitasking, floating windows. Unlike static split screens, a floating window can be moved around the display, resized, and even folded into a small icon in the corner.

To run an app in a floating window on Redmi 9C, open the menu of running apps, click on the program name, and select the Floating Window option. The app will open as a separate layer on top of the current one. You can run multiple of these windows at once, making the smartphone look like a desktop computer.

💡

Use a floating window for calculator or notes – so they will always be on hand while you fill out forms in the browser or work with documents.

Floating windows are controlled through the top of their header, where you can roll a window, open it to the full screen or close it, which is especially useful when watching YouTube or Twitch videos, when you need to communicate in parallel, without completely overlapping the main content.

Solving system problems and limitations

Despite the convenience, users may face a number of limitations. It often happens that when you try to enable split screen for a particular application, the system will give a message that this application does not support this feature, this is not a smartphone error, but a restriction set by the software developer.

Another common problem is the automatic closure of one of the applications when there is a shortage of RAM. Xiaomi Redmi 9C is equipped with 3 or 4 GB of RAM, which is a modest indicator for modern multitasking. The system can forcibly terminate background processes to free up resources for an active application.

⚠️ Warning: Do not attempt to use modified versions of system applications to bypass Split-screen restrictions. MIUI and lead to cyclical reboots.

To minimize memory problems, it is recommended to periodically clean the list of running applications, closing the ones you are not using right now, and in the battery settings you can turn off energy savings for important applications so that the system does not “kill” their process too aggressively.
